推荐答案

jni.h 文件是JDK安装的一部分。您可能没有正确安装Java JDK。从此处下载Oracle Java，或使用您的软件包管理器。

The jni.h file is part of JDK installation. You probably don't have Java JDK installed correctly. Download Oracle Java from here, or use your package manager.

如果已经安装了Java JDK，请将JAVA_HOME环境变量设置为指向JDK目录。

If you have Java JDK already installed, set JAVA_HOME environment variable to point to the JDK directory.
